And some more from yesterday:

Museumsinsel (Museum Island), Berlin (thanks to Jakob, his first!)
Medina of Essaouira (thanks meltwaterfalls, who made sense of the "rubbish maps" for the Moroccan medinas)
Medina of Marrakesh (meltwaterfalls again)
Meknes (meltwaterfalls again)
Brasilia (meltwaterfalls again)
Pyramids (Memphis) (thanks to Frédéric)
Wadi Al-Hitan (Frédéric as well: a rectangle!)
Abu Mena (Frédéric too)
Yakushima (c) Protected Planet
Shirakami-Sanchi (c) Protected Planet
Shiretoko (c) Protected Planet
Saint Catherine Area
Old Town of Ghadamès
Sabratha

In progress too are Cairo and the Berlin Modernism Housing sites.

I have also removed the Tropical Rainforest of Sumatra for now (it was copied from Protected Planet), as after a second look it was not done very well. (P.S.: put it back online after some adjustments to at least correct the offset and more follow the simplified lines in the official map instead of the wriggly lines of the national park boundaries, which also seem to have driven the Protected Planet artist crazy)

For the budding mappers, I have created a F.A.Q. on how to start creating your own core zone map and add POIs to it.

Meltwaterfalls 'finished' Morocco with:
Mazagan
Rabat
Tetouan

Fez is the only one missing, but it has no official map.

Palmeral of Elche - thanks to Jarek pointing out the error placing the dot way too far east (UNESCO website has it as well), asked meltwaterfalls to do the core zone as it is kind of a patchwork: https://www.worldheritagesite.org/list/palmeral-of-elche/

Added Tassili n'Ajjer (Protected Planet) as well.

Thanks to Digits for submitting Joya de Ceren (inc POIs). It has a very interesting core zone, much larger than I would have thought. It even has an automobile racing track in it.

And Frédéric advanced to Historic Cairo and Fujisan (25 locations! he must enjoy it)

Many thanks to mmarqz for sending in Mexico and some neighbouring Central American countries / sites.
It will take me a while to add them all since I am travelling at the moment, so this is just a heads-up to others who wanted to start on something Mexican: it's already in the pipeline.

Frédéric got addicted like me and he added Nara, Horyu-ji, Hiraizumi, Gusukus, Kofuns, Okinoshima, Tomioka and Shirakawa-go!

A chunk of Los Glaciares core zon is according to our map in Chile. Wouldn't it then be a binational WHS?

Thanks to Jakob for Berlin Modernism Housing Estates

Oh, I need to check, that shouldn't be of course. Will do when I am back home next week.

There is still a border dispute there, see https://en.wikipedia.org/wiki/Southern_Patagonian_Ice_Field_dispute. Google Maps doesn't draw a border here.
There are also some statements on this in the Report of the 5th session in 1981: https://whc.unesco.org/archive/repcom81.htm#annex3

Added Angkor, Koh Ker and the Cambodian Memorial Sites.

Thanks to Digits for Westminster including some fine POIs
https://www.worldheritagesite.org/list/westminster/

Added the first 4 of mmarqz's stash of Mexico:
Mexico City, Puebla, Oaxaca and Palenque

Looking at the map, I think the exclave around Templo de Santa María del Ex-Marquesado should be a different component.
